Pengukuran radioaktivitas Alpha dan Beta dari Batako dan Bata Merah

Abstract

The alpha and beta radioactivity of brick and concrete brick has been measured, with cx/P system counter model 2400. The alpha activity of two materials above oou.Ld be obtained as below: 1_ Concrete Brick: 2.Brick: Al = 0,021.10-2 pCi/gr D1 = 0,012.10 pC1/8r A2 = 0,014.10-2 pCi/gr. D2 0,014_10 pCi/gr A3 = 0,013.10-2 pCi/gr. D3 = 0,011.10-2 pCi/gr 81 = 0,020.10-2 pCi/gr D4 = 0,009.10-2 pCi/gr B2 = 0,015.10-2 pCi/gr D5 = 0,014.10-2 pCi/gr 333 = 0,018.10-2 pCi/gr Cl = 0,021.10-2 pCi/gr C2 = 0,032.10-2 pCi/gr C3 = 0,024.10-2 pCi/gr The beta activity of obtained as below: Concrete Brick: two materials above could be 2.Brick: Al = 12,16 pCi/gr D1 = 8,92 pCi/gr A2 = 12,70 pCi/gr D2 = 9,19 pCi/gr A3 = 12,43 pCi/gr D3 = 11,35 pCi/gr B1 = 16,22 pCi/gr D4 = 6,22 pCi/gr 82 = 13,78 pCi/gr D5 = 10,27 pCi/gr B3 = 10,00 pCi/gr CI = 17,84 pCi/gr C2 = 12,70 pCi/gr C3 = 14,86 pCi/gr Telah dilakukan pengukuran radioaktivilas alpha dun beta dari batako dan bata meiah, dengan peneacah sistem a/0 model 2400. Untuk aktivitas alpha didapatkan: 1. Batako: Al = 0,021.10-2 pCi/gr A2 = 0,014.10-2 pCi/gr A3 = 0,013.10-2 pCi/gr B1 0,020.10-2 pCi/gr 32 = 0,015.10-2 pCi/gr B3 0,018.10-2 pCi/gr Cl = 0,021.10-2 pCi/gr C2 = 0,032.10-2 pCi/gr C3 = 0,024.10-2 pCi/gr 2.Bata merah: Di 0,01_2.10- D2 = 0,01.4.10-2 D3 = 0,011_1.0-7 D4 = 0,000.10-7' D5 00i4.10 pCi/gr pCi/gr pCi/gr pCi/gr pC3/gr Untuk aktivitas beta didapatkan: 1 Batako: 2.Bata merah: Al = 12,16 pCi/gr D1 = 6,92 pCi/gr A2 = 12,70 pCi/gr D2 = 9,19 pCi/gr A3 = 12,43 pCi/gr D3 = 11,35 pCi/gr B1 = 18,22 pCi/gr D4 = 6,22 pCi/gr B2 = 13,78 pCi/gr D5 = 10,27 pCi/gr 133 = 10,00 pCi/gr Cl = 17,84 pCi/gr C2 = 12,70 pCi/gr C3 = 14,86 pCi/gr
